Hackipedia Posted June 20, 2012 Share Posted June 20, 2012 Hello pineapple enthusiasts! While waiting for my pineapple to arrive I have been brainstorming for ways to add functionality to it. The thought occured to me to connect a USB display to read the state of current operations without needing to connect via computer or other device. Combine this with a properly configured teensy with three push buttons and you can have controls to navigate menus on the display and enable/disable features on the fly without the need for anything besides the pineapple. While researching the feasibility of this idea I came across a guy who added a lcd display and gps to a router running open-wrt. http://h-wrt.com/en/doc/gps What do you all think? Is there any reason this wouldn't work? -Hackipedia Quote Link to comment Share on other sites More sharing options...
WatskeBart Posted June 21, 2012 Share Posted June 21, 2012 Would be a great mod for the pineapple. I can't see why it can't be done :) You could probably use the internal serial interface instead of the USB port ;) Quote Link to comment Share on other sites More sharing options...

I can't see why it can't be done :) You could probably use the internal serial interface instead of the USB port ;) I had considered that. However I worry about the serial port voltage levels. I believe I read that the pineapple uses 3.3v for the serial port. Most serial lcd displays I have seen use 5v. If I am wrong, however, that would be an excellent alternative. I just received my pineapple today so I will tear into it as soon as I get off work. I will be sure to post any additional info I come up with. -Hackipedia Quote Link to comment Share on other sites More sharing options...
Hackipedia Posted June 22, 2012 Author Share Posted June 22, 2012 So I just remembered I have this 4 X 20 lcd laying around that would be sweet to use for this. Hopefully I can manage to get the buttons functioning as inputs to cycle through menu options. Quote Link to comment Share on other sites More sharing options...

That's a really nice LCD indeed :) and the pineapple uses 3.3V :( but USB is still an option :) Quote Link to comment Share on other sites More sharing options...
Hackipedia Posted June 22, 2012 Author Share Posted June 22, 2012 So, a quick update. Turns out opkg can install lcd4linux and lcdproc however lcdproc is missing the driver for my specific display. Which is sad because I was able to use the buttons on my display to navigate menus when I was using lcdproc on my desktop. Might look into compiling it on the pineapple if I can find the source. Until that happens I am looking at lcd4linux. I have yet to get any output on the lcd using it though. I will post again when I have made more progress. -Hackipedia Quote Link to comment Share on other sites More sharing options...
